There is a new release of Project Freewheel. Scott has outlined what's in it on his It's Alive in the Lab blog:
Using a combination of Autodesk Design Review plus the 3D/2D ShareNow Add-in for Autodesk Design Review, lets you publish DWF files to Project Freewheel. This allows you to share your designs with those who do not yet have Autodesk Design Review. You can read more about ShareNow at:
Project Freewheel offers a markup capability similar to Autdoesk Design Review. Users can take advantage of it using just their browsers. So an electronic reviuew process based on Autodesk Design Review can be extended to others who might be on Linux, the Macintosh, or even a cell phone.
Sharing designs using applications in conjunction with software as a service solutions is just one of the ways that allow DWF to go beyond the paper.
